Title: Improvements in drilling machines
IPC: B23Q5/32
Filed: 1920-07-29
Abstract: 167,677. Smith & Coventry, Ltd., and Wright, I. H. July 29, 1920. Drilling-machines.-In a power-operated drilling- machine, the power feed spindle a<2> is operated through a coiled spring clutch b which frictionally engages a driving-member a during the working stroke, but is automatically released when the pressure on the drill ceases, or when the operating- handle o is turned backwards, or by the operation of an adjustable stop v. The spring b is expanded to grip the internal cylindrical portion of the driving-member o loose on the spindle a<2>, by the pressure of the adjustable stop e carried by a lever d pivoted on the member f fast on the spindle a<2>. The other end of the spring b abuts on the hardened part h attached to the member f, which can be turned in the ordinary manner to work the drill by pulling the handle o which fits loosely in a ring p coupled to the member f through a coiled spring r and stops to bold the handle o frictionally in any set position. For automatic action the lever d has a slot j engaged by a pin k on the crank m mounted loosely on the handle o which has a keyway loosely engaging the key n, so that by turning the handle o about its axis the lever d is operated to put the feed into action. When the pressure on the drill ceases, owing to the work being pierced, the spring b contracts, the play between the key n and the slot allowing this. The feed may also be stopped by raising the handle against the projection u on the lever d, or by an adjustable stop v engaging a projection w on the ring p.

Title: Sound reproducing system
IPC: H03G9/02
Filed: 1976-06-02
Abstract: 1518574 Gain control systems J. FRICKE and U. R. MœLLER 2 June 1976 22816/76 Heading H4R In a sound reproduction system for reproducing sound in a noisy environment the output level of the signal is increased and the dynamic range reduced when the noise level increases. As described when the ambient noise level, as picked up by a microphone 31, is low sound signals from a radio receiver 10 are fed via variable gain amplifier 27 to a power amplifier 14 for reproduction by a loudspeaker 18. As the noise level increases the gain of amplifier 27 is increased by about 4dB for each 10dB increase in noise level. At a predetermined noise level, threshold circuit 35 operates to insert a compressor amplifier 23 into the signal path, and at a second noise level a second threshold circuit inserts a second compressor amplifier 25. Other threshold circuits 43, 45, are responsive to particular frequency components in the noise to insert respective filters 51 and 53 in the signal path to increase the signal gain at frequencies predominant in the noise. The control voltage can be derived via a sample and hold circuit 31a which samples the noise when the signal being reproduced is at low level. In an alternative arrangement Fig. 3 (not shown) the frequency spectrum of the signal and the noise is broken up into a number of contiguous bands and the signal gain and compression in each band controlled in dependence on the noise level in the same band. In this system the signal is interrupted at regular intervals and the noise level sampled during the interruptions and a control voltage developed and held until the following interruption.

Filed: 1967-05-18
Abstract: 1,185,684. False-twist crimping yarn. TURBO MACHINE CO. 18 May, 1967, No. 23014/67. Headings DID and D1F. In a false-twist crimping process, a yarn is false-twisted by passing the yarn helically over a rotating friction roller with the yarn rolling along the roller in an axial direction to maintain the points at which the yarn reaches and leaves the roller substantially constant. In one embodiment the roller which may be of soft rubber is rotated by the yarn and is adjustably mounted so that the helical angle of the yarn around the roller may be adjusted. In another embodiment the yarn is adjustably guided to and from a driven roller and is passed helically therearound, and is then wrapped several times around the roller in order to for the roller to act as the drive means for the yarn. In a third embodiment the roller is circumferentially grooved and guide pins extend into the grooves so as maintain the yarn's arrival and departure points constant. Upstream of the roller the yarn passes through a heater and optionally a cooler. The yarn may be a twisted or untwisted single or multi-end yarn of nylon, polyethylene terephthalate, polypropylene, or a copolymer of vinyl chloride.

Title: Automatic thread joiner for continuous ring-spinning machines
Inventor: PRAT ROBERTO ESCURSELL
IPC: D01H15/013
Filed: 1963-06-11
Abstract: In the yarn-joining apparatus of the parent Specification, the movable platforms 45, 81 are replaced by a single movable platform 45, Fig. 1 not shown.  The position of this platform is determined by a lever 92 beneath it.  The lever is freely rotatable on a shaft 74, the weight of the platform being counterbalanced by a spring 130. The shaft 74 is rotated according to the position of the ring-rail by a lever 76 with a roller 77 resting on the rail.  The movement of lever 92 is derived from the shaft 74 under control of a cam 145. This, through a lever 133, Fig. 2 not shown, rotates, relatively to the shaft 74, a sleeve 132 having a recessed ring 143.  A lever 138 rotatable abut the sleeve has pivoted to it a two-armed lever 136a which is coupled to lever 92 by a pin 141 engageable with a member 142.  A similar arrangement 139, 140 couples lever 138 to a lever 137 fast with shaft 74.  As the ring-rail ascends, lever 76 turns shaft 74 to rotate lever 137, and bring pin 139 against member 140.  Levers 138 and 136a are thus raised to bring pin 141 against member142 to raise platform lever 92.  It is now necessary for the platform to discend to a limited extent so that a suction nozzle 87 can size the broken-end.  Cam 145 rotates the sleeve through lever 133 for the recess in ring 143 to register with the rear end of lever 136a and cause the latter to pivot to move pin 141 away from member 142 and allow platform lever 92 to descend.  The platform is raised again to withdraw the broken end, as rotation of cam 145 moves sleeve 132 to such a position that lever 136a moves out of the recess to move pin 141 against member 142.  Further raising of the platform for lifting the nozzle 85 to take the thread to the thread-guide is effected by rotation of the sleeve until a lever 134 fast thereon becomes coupled through pin 135 and member 148 with platform lever 92.  During the down-stroke of the traverse, the lever 138 does not descend because a pawl 79 on lever 138 engages a ratchet-wheel 80 fast with shaft 74. The platform lever is caused to descend, however, on the down-stroke, by the provision on lever 137 of a pivoted lever similar to lever 136a which co-operates with a recessed ring on shaft 74 similar to ring 143.  This pivoted lever is adapted to be coupled to lever 92 by a pin and member similar to the coupling 142, 141 between levers 92 and 136a

A flange 10c, Fig. 6, may be formed at the sheet edge so that the conduit 101 may be sealed by a continuous welding machine. Adjacent lengths of radiator may be joined, Fig. 9, by expanding adjacent conduit ends 105 and securing a tube 106 therein by capillary soldering or by brazing. The adjacent short edges of the sheets are joined by welding, soldering or brazing. The Provisional Specification refers also to the hooking of the edge being formed by drawing.
Patent GB-934926-A (GB)
Title: Lubricant injector
Inventor: JACKSON HAROLD ERNEST
IPC: F16N27/00
Filed: 1961-06-27
Abstract: 934,926. Lubricators. TECALEMIT Ltd. June 22, 1962 [June 27, 1961], No. 23284/61. Class 12 (3). In a one-shot lubricator, a metered quantity of lubricant is discharged at each pressure surge in a lubricant supply line. The lubricator 1, Fig. 1, is screwably connectable to the supply line 2 and has a body 3 with a cap 4 screwed thereto, a sealing-ring 5 being positioned therebetween. The body 3 houses a central tube 9 which has an axial bore 10 in communication with an outlet passage 11 in the cap 4, and radial passages 13 leading to an injector chamber. The latter is formed by a piston 14 which is slidably mounted on the tube 9 and seals against the inner wall of the body 3. The piston 14 is urged against a collar 15 on the tube 9 by a spring 16 and is displaceable by pressurized lubricant until a washer 17, which backs the flexible piston ring, abuts a loose spacer tube 18. An inlet passage 6 leads to the supply line 2 and is regulated by a non-return valve 7 having a U-type sealing ring 8 retained by a square-shaped flange 20 locked behind a cone 19. An outlet passage 11 in the cap 4 has a spring-urged ball 12 therein. In use, a pressure surge in the supply line 2 causes the valve 7 to move downwardly so that its cone 19 seals off the bore 10 of the tube 9. Lubricant leaks past the sealing ring 8 and forces the piston 14 downwards to displace a quantity of lubricant, equivalent to the swept volume of piston, through the outlet 11 and past the ball 12. When the lubricant pressure at the inlet 6 is reduced, the piston 14 is forced upwards by the spring 16, the valve 7 seats against the body 3 and the injector chamber is recharged through the bore 10 of the tube 9. In a modification, as shown in Fig. 2, a plug 21 is screwed into the inlet end of the body 3 and has a cylindrical socket therein which receives a spigot 22 of the valve 7. A sealing- ring 23 is placed between the body 3 and the plug 21. A member 24 is positioned intermediate the piston 14 and the collar 15 to keep the flexible flange of the piston in a sealing position. The cap 4 is replaced by an integral extension of the body 3.

Abstract: 1302334 Packaging bottles SIMPLIMATIC ENG CO 19 April 1971 [20 May 1970] 23292/71 Heading B8C Bottles 16 are fed in lanes 27 from a conveyor 10 on to a laterally movable grid (128, Figs. 1, 1A, 1B) on a support 18, Fig. 5, which receives a group of bottles and rotates to invert and deposit the group neck down in a case 210, the bottles 16 being held during rotation by a set of rubber suction cups 110 in the support 18. The latter may comprise pairs of back-to-back sets of suction cups 110, 110<SP>1</SP>, but as shown comprises a single pair so that it can receive a group of bottles as it is depositing another. Apertured levers 50 passing through a support end plate 58 detect the presence of a group of bottles on the support 18 and consequently activate a photo-electric detector 64, 66 which results in gates 70 rotating to prevent further bottle feed and in movement of the grid (128) to allow the group of bottles to drop on to the suction cups 110. The levers 50 which are mounted on a trolley 150 and an upper bottle guide 34 which may also be used for pressing the bottles on to the cups 110 are retracted by cylinders C and A respectively so that the support 18 can be rotated by a piston 17 through a gear and shaft assembly 168. Since the case 210 has a partition (see Fig. 1) the group of bottles is split into two by releasing a cylinder E to allow springs 202 to force apart two suction cup carrying platens 102. The case 210 is then lifted from driven rollers 234 by a U-shaped frame 266 to collect a freely slidable funnel 278 from a support 284 so that the bottles 16 which are released by momentarily passing compressed air through the cups 110 fall only a short distance through speed reducing rubber or metal funnel pockets 290 into the case 210. During loading, the clutch to rollers 234 is disengaged for safety and case grippers 222 (see also Fig. 6B) are opened by a piston H so that misalignment between the case 210 and bottles 16 can be accommodated. Loaded cases are lowered and removed by a take-off conveyer 215. The cases which are of folded cardboard or paperboard have their tops flaps folded down by a cam-operated anti-clockwise rotating finger 248 and a plough 247 as they are fed stepwise to the rollers 234 by chain conveyers 214, via gates and brakes defined by pistons F, G, I, J respectively (see also Fig. 6B). The latter may be supplemented by belt conveyers 218. The operation of the various switches is described and a flow diagram given (Fig. 7).

[Also in Division G3] Apparatus responsive to the density of a gas comprises a chamber 124 with a bellows 123, either the space 130 within the bellows or the space 127 between the bellows and the chamber being completely sealed and the other said space being open to a gas of unknown density, the sealed space containing a reference gas, and a servomechanism responsive to any difference in the pressures prevailing in the two said spaces, for adjusting the size of the bellows so as to make the said pressures equal. The movements of a ram 104 are transmitted to a lever 92 by means of the lever system shown. The ram 104 has a piston 106 opposite ends of which connect with a pipe 110 containing high pressure fuel. A servo-valve 111 is mounted within a sleeve 97, the valve being rotatable by an engine driven shaft 109. The servo-valve has a vent passage 113 communicating with a recess 114 which may in turn communicate with either aperture 115 or 116. The end of servo-valve 111 is connected by a transmission member 121 to a diaphragm 122 at the end of a sealed bellows 123. The gas under test enters the chamber 124 by apertures 126. The difference in pressure between the reference gas and the gas under test causes movement of the diaphragm and thus the servovalve which in turn moves piston 106 to expand or contract the bellows.
